Implication

This study reveals how lipid bilayer composition alters the physicochemical properties of exosome-mimetic vesicles, influencing peptide incorporation efficiency.

Key Points

Successful peptide incorporation achieved with vesicles containing 15% sphingomyelin and 40% cholesterol, improving drug delivery potential.
The exclusion of sphingomyelin or cholesterol led to low dispersion stability or ineffective peptide integration into exosomes.
Physicochemical analysis demonstrated that the membrane softness from cholesterol and the mobile boundary phase from sphingomyelin promote better peptide constitution.
Findings suggest that optimizing lipid composition is crucial for developing effective exosome-mimetic drug carriers based on specific requirements.
